In cryptography a blind signature, as introduced by David Chaum, is a form of digital signature in which the content of a message is disguised (blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature. Blind signatures are typically employed in privacy-related protocols where the signer and message author are different parties. Examples include cryptographic election systems and digital cash schemes.

Hacking Democracy is a 2006 Emmy nominated documentary film broadcast on HBO and created by producer / directors Russell Michaels and Simon Ardizzone, with producer Robert Carrillo Cohen, and executive producers Sarah Teale, Sian Edwards & Earl Katz. Filmed over three years it documents American citizens investigating anomalies and irregularities with 'e-voting' systems that occurred during the 2000 and 2004 elections in the United States, especially in Volusia County, Florida. The film investigates the flawed integrity of electronic voting machines, particularly those made by Diebold Election Systems, exposing previously unknown backdoors in the Diebold trade secret computer software. The film culminates dramatically in the on-camera hacking of the in-use / working Diebold election system in Leon County, Florida - the same computer voting system which has been used in actual American elections across thirty-three states, and which still counts tens of millions of America's votes today.

"None of the Above" has been provided as an option to the voters of India in most elections since 2009. The Supreme Court in PUCL vs. Union of India Judgement 2013 directed the use of NOTA in the context of direct elections to the Lok Sabha and the respective state assemblies. By expressing a preference for none of the above, a citizen can choose not to vote for any candidates who are contesting the elections. The vote does not hold any electoral value: even if a majority of votes are cast the candidate with the largest vote share would be declared the winner. The NOTA option was first used in the 2013 assembly elections held in four states, and the Union Territory of Delhi. Since its introduction, NOTA has gained increasing popularity amongst the Indian electorate, securing more votes than the victory margin, for instance, in the Assembly Elections in Gujarat (2017), Karnataka (2018), Madhya Pradesh (2018) and Rajasthan (2018). NOTA enables the voter to show their inacceptance for the fielded candidates.
